A star-ranking is the evaluation system that the Academy uses to judge a student's school work, Alice level and attitude. There are four rankings which are indicated by the number of gold stars on a student's collar.

No-Star: Students who are below-average. This is mainly reserved for children.

Single: Students who are pretty much average. Most of the students in the Elementary Division have this rank.

Double: Students who are more of an over-achiever than Singles but aren't exceptionally brilliant at either their studies or use of their Alice.

Triple: Students who usually are deemed as "over-achievers" and tend to excel at either their studies or use of Alice or both.

Special: Students who are considered the best of the best, signified by a lapel in the shape of a star enclosed in a circle (though rarely seen in the anime). Those who excel tremendously in their Alice and, if they care, their studies--to put in short, geniuses.

Each star ranking has its own monthly allowance rate:

No-Star: 5 Rabbits: (equal to about 500 yen or 5 US dollars)

Single: 30 Rabbits: (equal to about 3000 yen or 30 US dollars)

Double: 50 Rabbits: (equal to about 5000 yen or 50 US dollars)

Triple: 100 Rabbits: (equal to about 10,000 yen or 100 US dollars)

Special: 300 Rabbits: (equal to about 30,000 yen or 300 US dollars)

Be a good student if you want be a double star, triple star, or more^^
